exmapledeck2 = [1,2,3,4]


exampledeck2 = ['banana','apple,3,4]

Finaldeck already has 8 items, each one being an integer the idea is that every string in testdeck will need to be placed in the first integer found available in finaldeck.

You just need to use zip and enumerate together:

testdeck = ['apple', 'banana', 'napalm', 'ice','rock','death','plush','rush']
finaldeck = [1,2,3,4,5,6,7,8]

for index, (card, item) in enumerate(zip(testdeck, finaldeck)):
    if isinstance(item, int):
        finaldeck[index] = card

This is a single pass through both lists at the same time, terminating at the end of the shortest list.
